SANDS DELTA 3400 - SPRAYER CONTROLLER Introduction The instrument must be calibrated before commencing normal operation. Many settings are made only on initial installation e.g. from the 'SENSOR CONFIGURATION' screen. Other calibration settings may need to be altered on a regular basis according to the liquid being sprayed, nozzle types in use etc.
SANDS DELTA 3400 - SPRAYER CONTROLLER Data Entry Alpha-numeric values are entered via the right-hand keypad. You must press the key from 2 to 5 times to select the required letter. (Some keys have additional special characters not shown on the key legend).
If a single magnet is installed (as with a standard RDS Propshaft Sensor kit), the distance travelled for each turn of the prop shaft must be determined. To determine this distance, drive the vehicle forwards for exactly 10 revolutions of the prop shaft.
SANDS DELTA 3400 - SPRAYER CONTROLLER (ii) If 2 magnets are installed (as with a standard RDS Wheel Sensor kit), the distance is 1/2 the effective rolling circumference of the wheel. To determine this circumference, drive the vehicle forward in field conditions (with the implement attached if applicable), for exactly 10 revolutions of the sensed wheel.

SANDS DELTA 3400 - SPRAYER CONTROLLER Flow / Pressure Sensor Setup The sprayer control system is normally installed with both a flow sensor and a pressure sensor, and is set up for pressure-based regulation. The flow sensor provides a ‘true’ flow rate display compared to the calculated flow rate from the pressure sensor.

Start the sprayer and set the reference pressure (the typical working pressure) using the keys (fig.
SANDS DELTA 3400 - SPRAYER CONTROLLER Configuring the Control Valve 1. Sensor Configuration 5. Valve/Actuator UK607-09.PCX Figure 9a 2.4.1 Response The Response function sets the frequency at which the system adjusts the control valve when reacting to a change in forward speed. A lower setting results in a slower response, and increases the time taken for the application rate to match the target rate.
SANDS DELTA 3400 - SPRAYER CONTROLLER 2.4.6 Maximum Pulse This sets the maximum pulse length (milliseconds x 4) driving the flow control valve. Do not change this value from the default of 200.0 (800 ms). Configuring a Tank Fill Sensor A tank-fill sensor is optional.
SANDS DELTA 3400 - SPRAYER CONTROLLER Alarms Setup There are a number of alarms, most being programmable by the operator. Note that setting alarm limits to zero will disable that alarm function. Application Rate ‘UNDER APPLICATION’ This alarm is based on % variance from the target rate.
SANDS DELTA 3400 - SPRAYER CONTROLLER MAX. SPEED and MIN. SPEED These values set the thresholds for the forward speed alarms. They are automatically set according to the Target Speed on the "Nozzle Setup" screen, however, you can manually key-in another value via the alpha- numeric keypad.

RPM Setup Figure 13 UK572-11.PCX The following calibration procedure applies regardless of the speed output being sensed e.g. Engine RPM, PTO Speed, Shaft Speed, Fan Speed etc, depending on the particular installation.
SANDS DELTA 3400 - SPRAYER CONTROLLER Liquid calibration It is important to ensure that the flow / pressure sensors have been properly configured before doing a liquid calibration. NOTE: Liquid calibration is always done with water. When spraying denser liquids such as liquid fertilizers, after doing the jug test you should programme the correct density for that product, from the "PRODUCT SELECTION"...
